Enum CallingConvention

pub enum CallingConvention<'tcx> {
    Direct(Box<[Spanned<Operand<'tcx>>]>),
    Indirect {
        shim: Option<ShimType>,
        closure_arg: Spanned<Operand<'tcx>>,
        tupled_arguments: Spanned<Operand<'tcx>>,
    },
    Async(Place<'tcx>),
}

Describes how the formal parameters of a given function call relate to the actual parameters.

Variants

Direct(Box<[Spanned<Operand<'tcx>>]>)

1 to 1 mapping

Indirect

First argument is the closed-over environment, second argument is a tuple that contains the actual argument to the call of the closure function.

Fields

shim: Option<ShimType>

closure_arg: Spanned<Operand<'tcx>>

tupled_arguments: Spanned<Operand<'tcx>>

Async(Place<'tcx>)

An async generator, only has one argument which is the generator state.
